The Fontenelle Park project is one of a series of projects in the Minne Lusa Basin intended to remove and/or control flows in the combined sewer system and reduce the frequency, magnitude, and duration of overflows. These improvements expand the size and stormwater storage capacity of the lagoon and separate portions of the upstream basins to direct additional stormwater. With nearly three times the storage capacity, the lagoon reduces stormwater flow rates and volumes downstream, reducing overflows to the Missouri River. This project helped transform the park into a lush community amenity with trails, picnic areas and a lagoon habitat that can sustain aquatic life.
